Nowadays, there are numerous kinds of road base materials.
Therefore the selection of road base materials becomes one of the most important steps in highway construction.
Therefore, their life cycle cost model was over simplified in term of the decision and selection of the road base materials.
Therefore it was suitable for the selection of the road base materials with multiple influence factors.

However, in model test, correctly selecting model materials is the key to correctly simulate the prototype.[2] Currently, in consideration of few researches on similar materials of soft rock tunnel model test, and the problems such as high price of raw material, difficult availability of materials in market, and weak universality existing in the materials which can be used as reference, it is necessary to research and develop the similar materials with low price, wide source, and strong universality.
Research and development of model materials 2.1 Moulding process After selection of raw materials of model materials, the moulding way is very critical.
